/* From the mysql_change_user documentation:
This command resets the state as if one had done a new connect. (See Section 25.2.13, “Controlling Automatic Reconnect Behavior”.) It always performs a ROLLBACK of any active transactions, closes and drops all temporary tables, and unlocks all locked tables. Session system variables are reset to the values of the corresponding global system variables. Prepared statements are released and HANDLER variables are closed. Locks acquired with GET_LOCK() are released. These effects occur even if the user didn't change.
